PRESS FOR FLOOR-BOARDS.

avisar.

T c all whom it may concern:

Be it known that I, WILHELM BRUHN, carpenter, a subject of the German Emperor', residing at AltwI-Ieikendorf, near Kiel, Germany, have invented new and useful Improvements in Presses for F loer-Boards, of which t-he following is a specication.

rIhe object of the present invention is a tool serving to press the floor boards quickly and tightly together before they are nailed down to the joists.

Ihe work is quiet and rapid, all hammering in using clamps or pins for a provisional tightening` being unnecessary so that unnecessary vibration will not injure a ceiling made ready below.

In theaccompanying drawing Figure I shows the new implements' in side elevation. Fig. 2. is a plan view. Fig. 3. shows the saine in another position used for pressing home the last edge boards.

A screw spindle a with right and lett hand thread acts upon the nuts and 0, the nut b having a depending projection which is used as a clamping finger as shown. The nut c is provided with a pivot pin CZ to which are connected the links e and el and levers f' f, which latter' cross each other on a pin, common to both. The ends of the levers are bent downwardly and are provided with teeth, Yforming the jaws g and g. The spindle is provided with any convenient means for turning the same, and when the tool is placed upon a joist as in Figs. l and 2, the nut c will be made to travel till the teeth g g have firmly gripped the sides of the joist. Then the nut c becomes stationary and a further revolution of the screw spindle will press the nut with its clamping finger Specification of Letters Patent.

tightly against the edge of the tongued and grooved or other floor boardings, which will be nailed down subsequently. For the last strips near the wall the tool is turned upside down as shown in Fig. 3. The clan'iping finger of the nut l) attacks the edge oi' the boarding with the rear side and ajcleat /L is placed under the shank of the levers j f only to support them and to hold them in place. In this instance t-he nut c does not work at all and the opposite end of the spindle with the nut Z) is acting alone, the end of the spindle pressing against the wall. Therefore it is preferable to put a metal plate z' against the wall in front ol the spindle as shown.

I claim as my invention.

1. A tool for pressing Iioor boards together, composed of a spindle with right and left hand thread and of nuts, one provided with a clamping finger having acting front and rear faces, the other provided with a pivot, carrying means for clamping the tool to the sides of a joist substantially as described.

2. A tool for pressing floor boards together, composed of a spindle with right and left hand .thread and of nuts, one provided with a clamping finger having acting front and rear faces, the other provided with a pivot carrying links and pivotally connected levers with gripping jaws at the ends as described and for the purpose set forth.

In testimony whereof I aitix my signature.
